Astronauts have been warned not to play with their “rockets” in space – so they don’t get crewmates pregnant.
Self-pleasuring is banned in zero-G amid fears any floating semen could leave female colleagues up the duff.
The bizarre revelation came on US chat show king Conan O’Brien’s Needs A Friend podcast.

During recording, Conan asked a Nasa engineer if he had ever sent porn to the International Space Station. The boffin, identified only as Smythe, told him: “No, none of that.”
And O’Brien went on: “Does porn work in zero gravity? It goes everywhere.”
Smythe told him: “Three female astronauts can be impregnated by the same man on the same session... it finds its way.”
Nasa is getting ready to look at how sex in space might work as it plans for future Moon and Mars missions.
Academics from Concordia Uni in Montreal, Canada, say such research is “essential to the success of deep space missions and building off-world settlements.”
And last year, Amazon’s Jeff Bezos made headlines when he blasted into space aboard a willy-shaped rocket.
